hi,

we are coming over to our new house soon & are confused by differing information about the solar system. We are trying to work out the best forms of heating: 
oil rad - requires a solid power supply,
paraffin heater - expensive to buy, or
just use the fireplace?
I'm vering to the fireplace & oil rad, but only if the power will not struggle.

The house has been a holiday let & has a 12 panel, 12 battery system with a monster generator (to me!) that will automatically kick in when the batteries are depleted, or so I am lead to understand.

Friends are saying that the geni is for filling the batteries when there is little sun, but I am assuming, from what I have read & been told, that if the batteries run low at night the geni will kick in & power the batteries to power the house?

Help:)
